ELMO 780

Femtosecond Fiber Laser 780 nm

K E Y S P E C I F I C AT I O N S■ Wavelength 780 nm■ Output Power >140 mW■ Pulse Length <100 fs■ Repetition Rate 100 MHz■ Smallest Footprint - no external control
unit■ Detachable SHG unit - no heat dissipation in optical setup

Data■ Additional wavelength 1560 nm fiber
coupled with >180 mW and < 70 fs
pulse length

Menlo Systems’ fiber-based femtosecond laser sources integrate the latest
achievements in fiber technology into easy-to-use products. Menlo Systems’
unique figure 9® mode locking technology results in reproducible and long-term
stable operation. The ELMO 780 with its modular concept and its compact frequency doubling module is optimized for OEM integration and maximum versatility.
The system is maintenance free and engineered for 24/7 operation.
